What causes a red tongue with no coating?

Recently, I noticed that my tongue has become red and lacks tongue coating, which feels quite abnormal. I would like to ask, what could be the reasons for a red tongue without tongue coating?
Doctor's answer (1)
Dr. Zhang Liwen
A red tongue without tongue coating may be caused by factors such as internal heat ("shang huo"), glossitis, or spleen-stomach deficiency with cold. If there is a bacterial infection in the oral cavity, it may lead to glossitis, resulting in a red tongue and lack of tongue coating. In addition, deficiencies in vitamins or trace elements in the body can cause glossitis, leading to a red tongue and absence of tongue coating. Dietary adjustments are necessary in daily life.
